Saving & Exporting Guide
Learn how to save, configure, and print your cropped shipping labels. Choose formats, adjust quality, and set up thermal printers.
After adjusting coordinates and previewing pages, the final step is saving and exporting your file. PDF Cropper processes page changes in browser memory, utilizing WebAssembly libraries to compile output files. This guide details file options, resolution settings, and thermal printer setups.
1. Output Quality and Calibration
When exporting cropped files, choosing the right file type is essential for optimal results. By default, PDF Cropper exports in vector PDF format, preserving original shapes and text outlines without rasterization. This maintains barcode sharpness at any scale, ensuring reliable scans at carrier sorting hubs.
Ideal for thermal barcodes. No quality loss.
High resolution image export.
Vector PDF Format
Preserves vector graphic assets. Best for thermal barcode stickers.
PNG/JPG Image
Converts pages to high-resolution raster images (300 DPI). Best for digital sharing.
2. Custom File Naming & Auto-Download
For merchants processing high order volumes, maintaining clear file organization is essential. You can define a file naming template in the settings drawer (e.g. {original_name}_cropped), adding dates or crop indexes automatically. You can also enable "Auto-Download" to save files immediately after processing without manual preview steps.
3. Batch Saving & ZIP Exports
When processing multiple labels simultaneously, you can choose how to compile and save your output files. Choose "Single PDF File" to merge all cropped pages in sequence, or select "ZIP Archive" to compile each page as a separate PDF or image file inside a compressed ZIP folder.
Thermal Printer Calibration
To ensure clear prints on A6 (4" x 6") thermal paper, calibrate your printer's speed and density settings. High printing speeds can cause barcodes to print faintly, leading to carrier scanning failures during product dispatch.
